TYPEWRI'IING- MACHINE.

Application filed July 18, 1923, Serial No. 652,224. Renewed August 30, 1924.

This invention relates to manifolding typewriting machines oi the continuous billing type in which a composite sheet or web is fed around a cylindrical platen, the web comprising several plies oi work-sheets having successive corresponding forms printed thereon, said plies being sometimes separated from each other and sometimes joined at their side edges to form a tan-fold web, the various plies having carbon-sheets interleaved therebetween which are displaceable at intervals along the web to fresh sets of untyped forms. The invention relates more particularly to means to facilitate the relative displacing or shifting between the carbon-sheets sheets.

One term of this kind of machine is disclosed in the patent to l Vernery it Smith, No. 1,l32,055,'dated ltiareh 16, 1935. In said machine the platen is mounted in a swing frame by which it may be displaced upwardly from its normal typing position, so that that portion 01 the web containing the carbon-sheets may be straightened out preparatory to a carbon-displacing operation.

Another to 'm of machine for handling this kind of work is disclosed in the application of Jesse A. B. Smith, Serial No. 640,315, filed May 21, 199.3, in which there is provided means to so condition the web that there may be a relative shifting; between the carbon-sheets and the work-sheets without lifting the platen, the platen remaining always in its usual typing position. To this end there is provided in said Smith machine a curved table at the rear of the platen over which the web is conducted and from which it extends tangentially to the platen, when said table occupies its effective position. Said table is pivoted at one end nearest the platen and may be swung from a normally ineffective position to an eiiective position where the web may be stretched over said 'table, at which time the work-sheets may be fed forwardly to shift them while the carbon-sheets are held.

An object oi the present invention isto provide a curved table with a relatively fixed platen, said table being rotatable about its axis to move it from an ineffective position to an eii'ective position, and being effective while it is being rotated to withdraw the web around the platen to free the and the work carbon-sheets from the platen 'while the teed-rolls are released.

After the carbon-sheets have been freed from the platen, the table is held in its effective position while the work-sheets are advanced around the platen to shift them relatively to the carbon-sheets, a suitable gage bemg provided at the delivery side of the platen "to which the leading'edges of the typed forms are brought to determine the extent of shifting movement of the worksheets. The table may then be rotated to its lowermost position, and the web may then be fed to bring the leading edges of the worksheets to a second gage, thus bringing the carbon-sheets to the printing pointand the bottoms of the typed forms to a knife.

where they may be severed, the fresh set i of forms being in readiness for typing the I first line. I

It will be understood that by mounting the table at its axis, it may be kept above the bottom limits of the main frame of the machine, so that it may be set on a flat table with the typewriting machine.

Other features and advantages will here inaiter appear. i i

Figure 5 is a View similar to jFigureB and shows the table returned .to its lower position and the web advanced to the second gage bringing the carbon-sheets ,to typing position, and the bottoms of the typegtorms to the knife.

Type-bars 1O strike against the front ota revoluble platen 11, which is journaled in the usual maimer in a platen-frame comprising ends 12 and a rear paper-shelf 13. The usual front and rear feed-rolls 14 run on the under side of the platen. They may be released, or thrown from the platen, by" means of afinger-piece 15, connected by 'a link 16'to an arm 17, fast on ashaft 18. The shaft 18 is provided with flats, against which arms 19, forming part of levers 20, are held by spring-pressure. The levers 20 are pivoted onshaft 21, so that, when the finger-piece 15 is actuated, ,7 and the, arms '19 spread apart by turning of the shaft 18, thelevers 20, which support the pressure-rolls, are rocked on the shaft 21 to release the rolls. This roll-releasing structure is that commonlyfoun'd in the stand ard Underwood typewriting machine.

The work web, usually comprising superposed plies 22 (which'ma-y beseparate or which may form a fan-fold), is drawn up from a s'u-pply-spool, or from a zigzag folded pile (not shown), but which may be contained in a receptaclearrangedinthe rear of the typewriting machine and its stand 23. As the plies of the work-web rise from the supply at'24,'theyfirst pass through a carhonholder 25; and are there interleaved withthecarbons 26. Eachof thecarbons- 26has its rear end attached to one of two blades 27,'carried by standards 28 on the ends of a plate 29. The plate 29 is secured to a bar 30, forming the rear reach or crosstie of a frame which is secured to, and travels with,the platen-carriage 31. The ends 32 of the bar ers, offset to form ears,

which are secured by rivets orscrews to the sidepieces 34of this traveling frame. At their front ends, the side pieces 34 have offset cars 35, to which is secured, by screws ,or' rivets 36, a bar 37 which ties together the side pieces 34 at the forward end of the traveling frame. I The front cross tie or bar 37 is secured by screws or rivets '38, to brackets 39, in turn, secured, by screws or rivets r 40 to the usual rear cross piece or tie 41 of the platen-carriage 31. The platen-carriage rides in the usual manner on a rail 42 on the main frame43 of the machine; the main frame resting directly, asshown in Figure 1, upon the table or supportj23. For supporting the carbon-carrier traveling frame on the table 23, for movement with the platen-carriage in letter-feed and return directions, the table 23 is provided at its rear' with a rail 44, on which ride rollers 45,

5 ends at 48 under the rail 44, to serve as guards for holding thetraveling frame to the support 23. When the parts are in typing position, the work-plies 22, interleaved with the car- .bons pass upward from the carbonholder over a roller 49, and thence forward to and over a roller 50, journaled at 51 in the side plates 34 of the'traveling frame, above and at the rear of the paper table 13; the roller being so located-that the composite web may pass tangentially therefrom, down over the table 13 to the rear underface of the platen, whence it is guided around the platen, up across vtheprinting line, and along andin front of a staff 52, to which is adjustably secured, by means of a: set-screw 53, a gage 54, the purpose of which gage will hereinafter more fully appear. Between the rear roll 49 and the front roll 50 the composite web is in the form of a slack 55, which is suflicient to permit of line-space feed .of the composite web with the platen, in the typing operation, withoutcomplete elimination of the slack before the typing operation itself is completed. v i v After typing on a form-section of the composite web is completed, the feed-rolls 14;-are released,and thecomposite' web as a unit is withdrawn rearward around the platen until it assumes the position shown cuate formation,-and whichgis secured by screws or rivets 57 to cars 5'8'on the arms 59, 60 and 61 of a spider or standard, piv oted at 62, for rotary movement on" the side plates 34' of the traveling carbon-holder frame. It will be understood, from Figure 2, that there are two sets of arms 59, 60 and 61, one setat each side of the arcuate table 56, so that the latter with its supporting arms is, in effect, asection of a drum or cylinder, journaled at its ends in the side plates 34 of the traveling frame, soas to have movement with the platen-carriage in letter-feed and return directions with such traveling frame. The roller 49, over which the composite web first passes, as shown in Figure 1, after leaving the carbon-holder, is 1ournaled at 62 in the arms 59 of the rotary table; and the arms 59, 60 and 61 serve as guards, between which the side edges of the slack portion 55 of the web, in Figure 1 position of the latter, is held during the travel of the platen-carriage. It will also be noted that the convexity of the table 56, in its Figure 1 position, provides space for the slack 55. The Figure 1 position of the table is determined by engagement of the right-hand arm 61 of the rotary table with a pin 63 on the right-hand side piece 34 of the traveling carbon-holder frame.

For rotating the table 56 from Figure 1 to Figure 3 position, to release the carbons fromthe platen, there is provided a handle 64-, which is unitary with a rack 65, and which is pivoted at 66 to the left-hand side plate 3% of the traveling carbon-holder frame. The rack 65 meshes with a pinion 67, journaled at 68 to the same side piece 34; and the pinion 67, in turn, meshes with a pinion 69, fast on a stub-shaft 70, which forms the left-hand journal of the table 56, and to which the table 56 is made fast. Suitable collars 71 on the journals and 72 of the table 56 serve to hold the latter properly spaced between the side plates 3i oft-he traveling carbon-holder frame. It follows from the above that, when the operating arm 64 is drawn forward, from Figure 1 to Figure 3 position, the table 56, by means of the rack 65, pinion 67, and pinion 69, is swung clockwise, looking from the left, from Figure l to Figure 3 position. The table 56 is arrested in its Figure 3 position by the engagement of a stop-pin 73 on the right-hand arm 59 of the table, 56 with the end 74 of an ear '7 5 on the right hand side plate 34 of the traveling carbonholder frame.

During the tl11OW 'Of the table 56 to Figure 3 position, the roller 49 serves as an antifriction device for drawing out the web, without injury to the latter, and without tearing the carbons from their anchorage on the blades 27 of the carbon-holder. In Figure position of the table, it will be noted that the carbons and worlowebs lie smoothly on the table 56, so that subsequent shift of the work-webs forward with respect to the carbons, to clear thetyped forms of the webs from the carbons, and to pass the carbons to the next untyped forms, may be effected without cru'mpling or injury-to either the carbons or the work-plies. In this connection, it will be noted that, during the movement to the Figure 3 position, the composite web is at all times tangential to the table at the rear of the latter; and that, when in Figure position, the web extends tangentially from the forward end of the table to the platen. All sharp bends, such as might injure the same, are thereby avoided.

With the parts in Figure 3 position, the aforesaid forward shift of the work-webs with respect to the carbons is effected by first reapplying the feed-rolls 14:, and then turning the platen by one of the usual hand knobs. During this operation, the handle 64: is held by the operator in its forward Figure 3 position, so as to prevent movement of the table 56; and the carbons, being held by the carbon-holder and being in taut condition, cannot be advanced with the web. The lower end 76 (see Figure 4) of an arm 77, unitary with the gage 54L, serves as a gage for determining, by registration therewith of the leading ends of the work-webs, the amount of advance of the work-webs sufiicient to properly position the carbons in the next untyped form-sections of the worle webs.

It remains then to advance the composite web to a position for detachment of the leading typed form-section thereof, and to position the next untyped form-section for commencement of typing.

shown in Figure 5. lhe movement of the composite web to bring the leading ends of.

the work-webs to the gage 54 is efl'ected'by a further forward rotary movement of the platen; Preliminary to such further for-- ward rotary movement of the platen, and

also be suflicient to take care of the subsev quent line-space feed of the carbons as part of the composite web in the typing of the next form. To prevent catching ofthe web,

on the table 56, in its return to Figure lpositlon, the rear edge 56 of the same may be curved inward.

lVhen the leading edges of the leading typed form register with the gage 54, the rear edges of the leading typed form register with the cutting edge of a blade 78, so that, as indicated in Figure 5, the typed fornrsection may be severed from the rest of the Web by drawing the web against the blade. The blade 78, as shown in Figure 2-, is secured by rivets or screws 79 to brackets 80, in turn, secured by screws or rivets 81 to the end pieces 12 of the platen-frame. The brackets also serve to support a crossplate 82, to which the gage-staff 52 is centrally secured at 83. After detachment of the typed form-section, as indicated in Fig ure '5, or without detaching such form-section, typing on the next form may be commenced.

For guiding the web into properly centered position on the platen, side gages or plates 84, offset from clips 85, are adjust.- ably and removably secured to the papertab'le 13 by springing the curved ends of the clips 85 over the rolled upper edge of the table 13.

It will be noted, on reference to Figures 1 and 3, that in all positions of the rotary table or shell 56, the same is above the platform 23 which supports the machine, so that the platform may be extended horizontally rearward to the support thereon for the sub-carriage or traveling carbon-holder frame. It will also noted that no space between the rotary table or shell'and the.

It is forthis purpose that the gage 5%. is provided, a.

machine, or at the rear of the table or ro tary shell, is required for the slack in the web; the concavity of the table or shell itself providing the space for the slaclr. Since the table or shell in its carbon-releasing pothe shell may, in ellect be located within the shell or space which the latter occupies; and sincethe .web may be led directly and vertically up onto the end of the rotary ta ble, the whole presents an extremely com-' pact structure, requiring no space below the machine-platform, and requiring a space only slightly greater than the diameter of the shell at the rear of the machine.

Variations may beresorted to within the scope of the lnvention, and portions of the improvements may be used withoutothers.
